Zinc oxide (ZnO) is a highly efficient catalyst for the acylation of a variety of alcohols, phenols and amines with acid chlorides or acid anhydrides under solvent free conditions. Primary, secondary, tertiary, allylic and benzylic alcohols, diols and phenols with electron donating or withdrawing substituents can be easily acylated in good to excellent yield.
氧化锌(ZnO)是高效的催化剂,可在无溶剂条件下用酰氯或酸酐酰化各种醇,酚和胺。具有给电子或吸电子取代基的伯,仲,叔,烯丙基和苄基醇,二醇和苯酚可以容易地被酰化,具有良好或优异的产率。
